Andi Dorfman is shocked her ex Nick Viall is a surprise contestant on Kaitlyn Bristowe’s season of “The Bachelorette,” and is now warning her to “run fast” away from him. As Gossip Cop reported, Viall entered the competition on Monday’s show, much to the dismay of the current suitors who have been vying for Bristowe’s affection all season.

During the broadcast Dorfman tweeted, “One word…RUN! Okay two… RUN FAST! #TheBachelorette.” She added, “Really wishing I had the superpower of reaching through my TV right now. #TheBachelorette.” And she wasn’t the only one in shock over Viall’s return to “The Bachelorette.” Dorfman’s ex-fiance Josh Murray sent a series of tweets during the episode, and questioned Bristowe’s willingness to let Viall join the mix. “Ouch, I guess she’s not really into the other guys, what a slap in the face, but that’s her call,” he tweeted. “The tension in that group is gonna be insane, this is the MOST DRAMATIC SEASON EVER.”

As Gossip Cop noted, Viall was the runner-up on Dorfman’s season of “The Bachelorette,” and came under fire after he revealed to the world during the “After The Final Rose” special that he had sex with Dorfman in the Fantasy Suite (see photo above). During Monday’s show with Bristowe, Viall bombarded a group date in New York, and Bristowe eventually asked him to join the show. It was revealed that Bristowe and Viall had been texting each other prior to her becoming the latest Bachelorette. What do you think of Viall becoming a contestant again?
